The water heater is a large tank that normally heats up the water to temperatures. As we use the heated water stored in the tank, cold water enters the tank to replace it and is then heated. The thermostat detects the drop in temperature and turns on the elements to begin heating up the cold water. Electric water heaters have two elements, an upper and a lower one.
